Milan Kundera emphasizes the vital role of friendship in maintaining our identity and memory. He suggests that our interactions with friends help preserve our past experiences, which are essential for the cohesion of our self. Just as plants need water to thrive, our memories require nurturing through regular contact with those who share our history. This connection prevents our sense of self from diminishing over time.

Furthermore, friends serve as reflective surfaces that allow us to view our identities more clearly. By engaging with friends, we can better understand ourselves and the memories we hold. Their presence acts as a constant reminder of our shared experiences, allowing us to maintain a fuller sense of who we are. Ultimately, the act of remembering and sharing with friends is crucial for our personal growth and stability.
